Characteristics of paired injections into cerebellar cortex of CP. Paired injections involved a Retrobeads and a BDA injection at approximately the same cortical location. Physiology refers to the stimulated part of the ipsilateral hindlimb or hindpaw that evoked the largest responses on the cerebellar surface where the paired injection was made. Zebrin band in brackets indicate injection sites that have a small amount of spread to that zebrin band. For injection sites that spanned two zebrin bands, “>” indicates in which zebrin band the injection site is predominantly located. Laterality index is a normalized measurement of injection site location relative to zebrin band 4+ (see Materials and Methods). “D” indicates that the laterality index could not be calculated because the section at the core location of the injection site was damaged. GB, green Retrobeads; RB, red Retrobeads.
